Abstract

The present invention relates to a mounting system and method for enhancing implant fixation to bone. That is, the present invention relates generally to the field of orthopaedics. Various embodiments of the present invention relate to the replacement (totally or partially) of a joint. In one example (which example is intended to be illustrative and not restrictive), the present invention provides a modular system with different anchoring mechanisms for optimized fixation of a joint implant to the bone (wherein 'optimized' fixation may be as desired by a surgeon).
